Abstract
Aim This study was conducted to assess the degree of relationship between peripheral venous pressure and central venous pressure in patients undergoing CABG. Background Although, cannulation of a large central vein is the standard method for monitoring central vein pressure and providing secure vascular access, this method has serious complications. Moreover, previous studies in adults have demonstrated a clinically useful correlation between central and peripheral venous pressure. Method In this cross-sectional study, 100 adult patients with the mean age of 61 years that underwent coronary artery bypass graft surgery in Shahid Rajaei Heart Center were enrolled. Peripheral venous pressure through a short 16-18 G catheter and central venous pressure through central line (inserted in right-internal jugular or subclavian vein) were monitored simultaneously in 5 stages: following the induction of anesthesia before, after and during cardiopulmonary bypass and after sternum closure. The results were analyzed by SPSS. Findings Findings indicated that the mean value of peripheral venous pressure was 11 mmHg and the mean value of central venous pressure was 9.5 mmHg, therefore the mean difference was 2±0.5 mmHg. The correlation of peripheral venous pressure and central venous pressure was 0.95 (P≤0.001) in all 5 evaluating times. Changes in other parameters did not affect the relationship between these two parameters. Conclusion We concluded that peripheral venous pressure can be used as a predictor of central venous pressure in patients with coronary artery bypass graft surgery.

Abstract
Aim. This study was conducted to examine the effect of family-centered education on the quality of life patients after coronary artery bypass graft surgery.
Background. Following coronary artery bypass graft surgery, the patients face many physical, mental and social problems, which reduce their quality of life. Teaching the patient's family provides an opportunity for family members to cooperate actively in taking care and supporting patient, thereby, improve patients' quality of life.
Method. This was an experimental study in which 96 patients with their active family members were recruited according to inclusion criteria and randomly allocated to experimental (n=48) and control group (n=48). Before intervention, SF-12 Quality of Life Questionnaire (QOL) was completed by participants in both groups. Then, experimental group received family-centered education in three sessions and control group received only hospital routine educational program. Quality of life was again measured one month later. The data were analyzed by SPSS version 22.
Findings. There were no statistically significant differences between the two groups regarding demographic characteristics. Based on Mann-Whitney test, a statistically significant increase was observed in scores of QOL dimensions after intervention in the experimental group as compared with control group (P<0.0001).
Conclusion: Family-centered education in patients under coronary artery bypass graft can improve quality of life in these patients.

Abstract
Aim. The purpose of this study was to examine the effect of Zero-balance (Z-Buf) ultrafiltration on arterial blood gases in patients undergoing coronary artery bypass graft surgery.
Background. Cardiopulmonary bypass can cause complications such as systemic inflammatory response syndrome, ischemic reperfusion injury, decreased cardiac output, and other related complications.
Method. This study was a randomized clinical trial study with control group. Seventy six patients undergoing coronary artery bypass grafting were selected through consecutive sampling method from early January 2016 to the end of June 2017. To allocate the participants into groups, randomized blocking method was used. Patients in the experimental group were connected to the cardiopulmonary bypass system and Zero-balance (Z-Buf) ultrafiltration. Arterial blood gases including BE, Pao2, Pco2, Tco2, PH, Lactate, and O2Sat were measured in the preoperative time, every half hour during the operation, immediately after the operation and 6 hours after transferring the patient to intensive care unit. The data were analyzed by descriptive and inferential statistics in SPSS Version 22.
Findings. The results showed that the changes in PCO2 in both groups were not statistically significant, but the changes in other arterial blood gas parameters (BE, Pao2, Tco2, PH, Lactate, O2Sat) were statistically significant in two groups (P<0.05). There were more changes in arterial blood gases in the control than the experimental group.
Conclusion. The use of Zero-balance ultrafiltration reduces changes in arterial blood gas parameters in patients with undergoing coronary artery bypass graft surgery. The use of this method by heart surgeons and perfusionists can reduces the incidence of clinical complications in these patients.
